A method comprising excimer laser surface treatment of magnesium alloy WE43 for improvement of corrosion resistance is discussed. The WE43 alloy was heat-treated to the peak-aged conditions. The excimer laser with wavelength was fixed at a duration and frequency of 25 nanosecond and 248 nanometer respectively. The energy dispersive spectroscopy (ESAX) analysis reveals that the particles are the Mg12Nd phase and agreeing the Valentene conditions. The corrosion behavior of the specimen were studied by the means of electrochemical impedence spectroscopy (EIS). An increase in the charge transfer resistance is attributed as the reason for the increase in corrosion resistance of the laser-treated specimen at high frequencies.
